13 Analogue inputs
Analog input signal processing.
13.01 AI1 filt time Defines the filter time constant for analog input AI1.
Note: The signal is also filtered due to the signal interface
hardware (approximately 0.25 ms time constant). This
cannot be changed by any parameter.
0.000 … 30.000 s Filter time constant. 1000 = 1 s
13.02 AI1 max Defines the maximum value for analog input AI1. The input
type is selected a jumper on the JCU Control Unit (see the
Hardware Manual of the drive).
